FRANZ X. XVAGNER, OF NEV YORK, N. Y.

TYPE-WRITING MACHINE.

SPECIFICATIONforming part of Letters Patent N 0. 454,692, dated June 23,1891. Application filed December 19, 1889. Serial No. 334,294 (Nomodel.)

To all whom it may concern.-

Be it known that I, FRANZ X. WAGNER, a

citizen of the United States, residing at New York, in the county andState of New York, have invented new and useful Improvements inType-Vriting Machines, of which the following is a specification.

This invention relates to improvements in type-writing machines; and theinvention consists in certain details of construction set forth in thefollowing specification and claims and illustrated in the accompanyingdrawing, in which- Figure 1 is a front elevation of a typewritingmachine. Fig. 2 is a rear. elevation of Fig. 1. Fig. 3 is a plan view ofFig. 1. Fig. 4 is a section along a: a", Fig. 5. Fig. 5 is a sideelevation of Fig. 1. Fig. 6 is a section along y y, Fig. 1. Fig. 7 is aside elevation of arms which assist in the motion of certain parts. Fig.8 is a detail View of the spacingkey and contiguous parts.

In the drawings, the letter A indicates a suit able base or support.

The platen or paper-carrier B may be of any suitable well-knownconstruction, adapted to travel along and swing on the guide-rod O, andbeing also supported by a roller or wheel D, traveling along a suitabletrack E. In the drawings the platen B is shown mounted in a carriage,the essential parts of which may be of any well-known constructionas,for example, a back or back plate E, Fig. 6, having arms or lateralframe-plates S, through which the axle of the platen passes, and fromthe back R extends an arm T, on which is mounted the wheel D, and saidback R also has arms or lugs U, which are perforated for the receptionof the guide-rod C, so that the carriage with the platen can swing andtravel on said guide-rod. A spring-drum F, con nected to the platen by astrap or band G, may be used in connection with a rack H and feed-dog Ito feed the platen.

The type are supported by a carrier, wheel, or cylinder K. Said carrierK is capable of a rotary motion, by which the required type is broughtopposite to the platen, and of a linear or printing motion, by which thecarrier brings the required type against the platen, so as to print.Said type-carrier may also have two or, more rows of type, in whichsaidkeys when depressed by the operator imparts motion to a bell-cranklever N O, fulcru med at P, there being one bell-crank lever for eachkey. Each arm N of the bell-crank levers has a lug or shoulder V, Fig.3, which extends under the. key L, so that the key rests on saidshoulder V and arm N, so as to move the bell-crank lever N O. Thedepression of a key moves the corresponding bell-crank so as to swingits arm 0 backward or toward the platen B. The arm 0 is extended up farenough to strike the actuating-bar Q, Fig. 7, so that the backwardmotion of the arm 0 is communicated to the actuating-bar Q, from whichan arm R extends to the slide S, so that said slide moves with the barQ. The arm R is rigidly fixed to the bar Q, so as to move with the same.Said bar- Q is supported by arms T, fulcrumed at P, and said arms T areextended so as to form lugsU for the support of the bar V, to which anarm W is secured. The arms T may be fulcrumed at any'convenient pointalong the shaft P. In the drawings the arms T are shown arranged in twosets, one set on each side of the type-carrier and having three arms Tin each set, one. arm

of said set being located near the outer part of shaft P, another armbeing located near the type-carrier, and the third arm beingintermediate to said two arms. To the arm W is connected the restoringspring X, and when the depressed key is released the restoring-spring Xmoves the key with the actuating-bar Q and slide S to the startingposition. The slide S has teeth or grooves Y, which engage lugs Z,connected to the toothed wheel a, fixed to the axleb of the type-carrierK. Each slide S is supported by a pivot WV, connecting the slide S withone" of the arms R, and by a pivot X, fixed to a suitable part of theframe. The slide S, as shown in the drawings, can be readily formedfroma piece of sheet metal suitably bent and shaped or cut to form theteeth Y and provided with a slot for the reception of pivot X, as seenin Figs. 5 and 6. When the slide S is moved toward the platen, the teethY rotate the lugs Z and type-carrier K, so as to bring the typecorresponding to the moved key opposite to the platen, so as to be readyto print. The return of the slide S restores the type-carrier to itsstarting position.

For different types the carrier must rotate more or less to bring saidtype opposite the platen. For this purpose the arms N of the leversN Oare of varyinglengths. The longer arms N, being in contact with the keysL nearer to the fulcrum M, will not receive so great a degree of motionfrom the depression or swing of the keys as the shorter arms N, which,being in contact with the keys L, farther from the fulcrum M, receive somuch more motion from the swing ofthe keys on the fulcrum M. The greateror less motion of the various arms N and levers N 0 causes greater orless motion of the slide S and consequent variety in the rotation of thetypecarrier K. When the rotation of the typecarrier has ceased, saidcarrier is given a linear or printing motion to carry the required typeagainst the platen, so as to print. To give this printingmotion, thefollowing mechanism is employed Links 0 extend across the machine, therebeing one link for each'key L and lover N 0. As seen in Fig. 7, eachlink a is made to extend across the frame A, so as to be supported bysaid frame, said frame having slots or recesses, Fig. 1, into which thelinks 0 are set and in which said links are guided. When a lever-arm Oswings backward, a pin 61 on said arm 0 presses against aliftingshoulder or incline 6, Figs. 5 and 6, on the link 0 and raises the link,so as to bring the connecting-shoulder f on said link in the path of theactuatingbar Q. As the actuating bar moves back it strikes against theshoulder f and forces the link backward. As each link 0 is made to abutagainst the printing-bar g, Fig.7, this backward motion of the link isimparted to said printing-bar g, which is connected by a link It, Figs.5 and 6, to the axlebof the typecarrier, so that the backward motion ofthe printing-bar is communicated to the typecarrier to give the printingmotion to said type-carrier. To the printing-bar g are fixed one or morearms Y, Fig. 7, to which the link h is connected by a pivot Z, so thatthe link It partakes of the motion of bar g.

As the printing motion of the type-carrier consists in the type-carriermoving backward toward the platen, and during such printing motion ofthe type-carrier the slide S and the type-carrier move backwardsimultaneously, said slide during the printing motion of thetype-carrier will not rotate said carrier.

'As the type-carrier must rotate more or less to make different typesface the platen, the connecting-shoulders f of the various links 0 areplaced farther from or nearer to the starting-point of theconnecting-bar Q, so thatthe connecting-bar will not move a link 0 togive the printing motion to the type-carrier until the proper type onsaid carrier faces the platen. That link 0 which is to be actuated, asalready stated, is raised by the pin 01 and incline 6, so as to lift itsconnecting-shoulder into the path of the actuating-bar Q, while thelinks which are to remain at rest are not raised, so that the bar Qswings over said links without imparting motion thereto. Theprinting-bar g is supported by arms t', fixed to a shaft 76, swinging onthe frame or support, and from the shaft extends an arm Z, Figs. 2 and6, to which is secured a restoring-spring m to restore the printing-barand the links 0 to the starting-points at the proper moment. Theprinting motion of the type-carrier should not occur until the propertype faces the platen. To prevent such printing motion at impropermoments, a stop it, Figs. 5 and 6, is provided, which prevents theprinting motion of the link h and type-carrier K until the proper time.This stop 11., as seen in Figs. 4, 5, and 6, when in its normalposition, projects up through an eye or perforation in the link 71, soas to prevent said link sliding backward. W hen the printing motion isto occur, the stop n is withdrawn. This stop it is connected to auniversalbar '0, Figs. 4, 5, and 6, and as a key L is depressed said keypresses on the universal bar 0 to withdraw the stop it. The connectionbetween the stop n and bar 0 is readily formed by providing the bar 0with a nose 0., Figs. 5, 6, and '7, which nose projects into or passesthrough an eye or perforation in the stop it, so that the descent of thebar 0 will depress the nose 0. and withdraw the stop it. When the key isreleased, a restoring-spring, Fig. 6, carries the stop back to itslocking position. This restoring-springp is shown in Figs. 6 and 7, andas the stop or and bar 0 are connected, as described, the return of thestop by the spring 19 will return the bar 0 to its normal position afterbeing depressed.

The stop it is provided with an arm (1, connected by a pin 0" with anarm .5, con nectedto the feed-dog I, so that the oscillations of thestop n oscillate the arm 3 and actuate the feed-dog. The feed-dog ismounted on the pivot b, Figs. 2, 5, and 6, and said feed-dog may be ofany suitable well-known construction. In the drawings the feed-dog isshown composed of two blades I, slightly separated or out of line withone another, as seen in Fig. 4, and as one of said blades passes out ofgear with the rack H and the other blade passes into gear with said rackthe platencarriage moves or slips along a slight distance, sufficient toform a space between two letters.

During'the printing motion rotation of the type-carrier is to beavoided. For this purpose a stop If is fixed in position to be engagedby the toothed wheel a, fixed to the type-carrier shaft b, when saidshaft 1) moves the type-carrier toward the platen B. while the toothedwheel a is in engagement with the stop t rotation of the type-carrier isprevented. When the type-carrier, with its shaft 1) and wheel a, movesback to the startingpoint, the wheel a is carried clear of the stop If,and the type-carrier is again free to rotate.

The universal bar 0 is supported by swinging arms u, swinging on thefulcrum M. Said universal bar 0 is shown as having one or more arms '21,Figs. 3 and 4, from which extend pins w, on which press arms A,extending from the arm T, Fig. 7, so that the arms T A in each case forma bell-crank lever. As the bell-cranks T A are moved by the backwardswing of the actuating-bar Q, the arms A depress the pins 10 and arms'v,so as to depress the universal bar 0. The return movement of theuniversal bar by means of the arms A '0 assists the return of theactuating-bar Q to its. starting-point. As the arms A, in connectionwith the arms T, form a bell-crank lever, and as the bar Q is connectedto the arm T, the return movements of the arms A will cause the arms Tand bar Q to return to the starting point.

The type-carrier K is inked by the inkingrollers B, pressed against thecarrier by spring-arms C. The arms C1 are supported by an arm D, which,with the type-carrier shaft 1), has a common support E. The arm D haslateral arms 0, to which the springarms 0 are connected by pivots d, andto said arms 0 are soldered or fixed lugs c, Fig. 5, which lap over thearms 0 to prevent excessive outward motion of said arms 0 and to holdsaid arms 0, with their rollers 13, against the type. The support E issimply a rod or bar fixed to the arm D and to a sleeve or tube f, inwhich the shaft 6 is supported, and in which it can rot-ate. The arm Dis guided in rising and falling by a screw or stud g, fixed to a frame Aand passing through a slot in the arm D, Fig. 1. The lower end ofshaft 1) is supported so loosely in the bottom of sleeve f that theupper end of the shaft has enough freedom for lateral motion to move thetype-carrier against the platen. The sleeve f is guided in its risingand falling motion by suitable perforations or ways in the frame A. Bymaking this support E capable of rising and falling or an axialmodon-that is to say, a motion in the longitudinal direction of the axleor shaft b-the typecarrier can be raised and lowered, so as to bringdifferent rows of type into the printing line.

A lever F, fulcrumed at G, can be made to raise the type-carrier. Thislever F, as seen in Fig. 1,has one arm passing under the support or rodE, so that the upward swing of this lever-arm will raise the support E,together with the shaft b and type-carrier. This lever F can be actuatedby a finger-button H, attached directly to the lever F or by a key I,made to act on the said lever. The

- key I is shown fulcrumed or pivoted to the frame A at 7i, Figs. 3 and4E, and said key passes over or rests upon the lever F, so that thedepression of the key will swing the lever. In practice it will be foundconvenient to arrange the key- I so as to actuate the lever F to'acertain degree to bring one row of type into the printing-line and toarrange the finger-button H so as to actuate the lever F to a differentdegree to bring another row of type into the printing-line. When thelever F is released,'a restoring-spring K brings the lever F and thetype-carrier K back to the starting-point. The lugs Z on the toothedwheel a of the type-carrier shaft 19, are so long that the rise and fallof the shaft 12 does not disengage the lugs Z from the slides S.

About the platen B pass flexible bands L. One end of each of said bandsis secured to the supporting-frame of the platen, and'the other end ofeach of said bands is secured to a spring M, seated on a bar N,supported by the supporting-frame of the platen. The springs M. hold thebands L snuglyagainst the platen. The springs M, as seen in Fig. l, arecoiled about the bar N, and one end of each spring is secured to a stud11, fixed to said bar, and the other ends of the springs are secured toarmsk, swinging on said bar N, and to which arms the free ends of thebands L are secured. The tension of the springs causes the arms k topull on the free snugly about the platen. When a piece of paper ispassed onto the platen, the edges of the paper come between the platenand the bands L, so that said bands hold the paper snugly against theplaten.

The spring-drum F for moving the platen is shown as having its axle 0extending through the machine, so that said axle has a firm seat,andsaid axle can be provided with .a ratchet and pawl in any well-knownway to enable the spring of the drum F to be put under proper tension.

In addition to the restoring-sprin gs already ends of the bands L and todraw said bands IIO named, each key L can be provided with its 7individual restoring-spring P. In Figs. 4 and 5 the springs P are showncoiled about the fulcrum or bar M and having one end braced againstframe A and the other end passing under a stud Z on the key, so that thetension of the spring presses the key upward. The keys L are shownarranged in two sets, one set on each side of the type-carrier K. Eachset of keys acts alike in rotating the type-carrier and imparting motionthereto, and each set of keys is provided with its actuating-bar Q andslide S. One slide S rotates the typecarrier in one direction andtheother slide S rotates the type-carrier in the opposite direction.

The spacing-key Q is made to actuate the universal bar 0 so as toactuate the feed-dog I, and, if desired, said spacing-key can. also bemade to rotate the type-carrier, so as to see cure inking of saidcarrier; but said spacingkey should not be made to actuatetheprinting-bar 9, so that during the spacing operation the type-carrierdoes not have any printing motion. The spacing-key can readily beprevented from actuating the printing-bar, since by not providing anylinkcfor the spacing-key said key cannot communicate motion to theprinting-bar. The spacing-key is mounted on fulcrum M, and is made topass over and press on the universal bar 0 the same as any one of thekeys L, and by providing the spacing-key Q with its bell-crank lever N 0said key Q when operated will actuate the bar Q and rotate thetype-carrier the same as a key L.
